Turkish merchants must collect a TC ID number from individuals or a company title, tax office and tax number from businesses to issue a valid e-invoice. On standard Shopify you cannot edit checkout, so this data is hard to gather. Sepette Fatura adds an invoice form to the cart page. Customers choose Individual or Corporate, enter their details, and the numbers are validated before they continue. The information is saved to the order, so it is ready for your e-invoicing. No Plus required.

• Invoice form on the cart page — works without Shopify Plus
• Individual and Corporate modes with the right fields for each
• Automatic validation of TC ID and tax numbers before checkout
• Details saved to each order, ready for your e-invoice software
• Customers can't reach payment until invoice details are filled
